Important Dates

Based on recommendations made by the JWST Standing Review Board, NASA is re-scheduling JWST’s launch window for 2021. Given those circumstances, STScI will delay the Cycle 1 GO/AR proposal deadline until no earlier than February 1, 2020.

A revised proposal schedule will be developed in consultation with the JWST Users Committee, the JWST Project and representatives from the European and Canadian Space Agencies. Proposals already submitted in response to the Cycle 1 Call will not be carried over and will need to be resubmitted.
